IMPROVEMENT IN BUTTONS FOR CURTAINS.

Specification forming part of Letters Patent No. 222,692, dated December16, 1879; application filed October 11, 1879.

ence being had to the annexed drawings, making a part of thisspecification, and to the letters and figures of reference markedthereon.

Figure 1 of the drawings is a representation of a face of my button andfastener, showing the same applied to a curtain; and Fig. 2 is avertical sectional view.

The nature of my invention relates to buttons especially designed forcarriagecurtains,

although I may employ the same for the purpose of buttoning downtent-canvas or ourtains other than those employed upon vehicles.

The object of my invention is threefoldfirst, to secure the curtain upona button by means of spring-locking mechanism; second- 1y, to provideagainst the accidental unlocking of the spring-locking device; and,finally, to prevent the curtain from tearing out at its eyelet.

To this end my improvement consists in a button comprising a shankhaving a springcatch, a detachable head consisting of a sleeve whichfits over the shank and spring, and a cup-shaped guard, which is formedupon one end of the sleeve, and employed for the purpose of protectingthe spring from accidental pressure, the said shank being formed with arecess for the spring, a screw-threaded or pointed end, whereby it iseither screwed or driven into the carriage-frame, and a flange orshoulder, which bears upon said frame when the shank is fitted thereto.The curtain is provided with a metal eyelet, which fits over the shankand spring, and which, when the head is adjusted upon the shank, will besecurely maintained thereon.

In the drawings, A designates the curtain, and B its metal eyelet, whichfits over the button-shank C. This shank has a screwthreaded or pointedend, which penetrates the wood, and a flange, D, which bears upon theframe E, and which also constitutes a bearing for the eyelet, which, inpractice, should be made somewhat smaller relatively to the diameter ofthe shank than that herein shown.

F designates a spring, which is provided at one end with a hook orcatch, and which is fastened at its other end to the shank (J. The shankhas a longitudinal recess, G, into which the spring will be compressedwhile the sleeve H of the button-head is passing over the same. Thissleeve H is formed with a flaring or cup-shaped end, I, so that when thehead is fitted down upon the shank the catch end of the spring will beprotected from accidental pressure and consequent displacement of thehead.

Fig. 2 clearly illustrates the parts fitted together.

To remove the button-head the'spring is pressed back within the recessin the shank, and the sleeve slipped off.

What I claim is- 1. In a carriage-curtain button, the shank (1, springF, secured to the shank, aud'the detachable head, comprising a sleeve,H, with a hollow cup-shaped end, I, substantially as specified.

2. In a carriage-curtain button, the shank 0, adapted to be screwed ordriven into the wood, and formed with a flange, D, and a lon gitudinalrecess, in combination with the spring F, formed with a catch upon itsouter end, and the detachable head, composed of the sleeve H, with ahollow cup-shaped end, I, substantially as set forth.

3. The sleeve H, with a hollow cup-shaped end, I, the recessed shank Q,and the spring-
